A hang hole is a handy feature that allows you to hang your product packaging via hooks on retail shelving. The round or sombrero hang holes are two of the most popular types that make it easy to display your products in a retail setting. This feature is especially useful for products such as snack foods, pet treats, and health and beauty items that need to be easily accessible and visible to consumers. With a hang hole, your packaging not only stands out on the shelf, but it can also be conveniently stored without taking up too much space.
